 Woo/soni, Paliiirtis intcgrifoliiis and Cdastro^hylluvi JVeiv- 

 berryanum, and all except possibly Paliiiriis and Chondrites 

 with well-characterized remains. Of the numerous species 

 which are identical with those of the Dakota group of the 

 West only eight are confined to the Dakota and Matawan 

 formations. There are twenty-three species identical with 

 Dakota group forms, but it may be remarked that the latter 

 horizon is not precisely defined and its flora is exceptionally 

 well known. 



Fifteen of the Matawan species are found in the Raritan 

 Cretaceous of the islands ; nine occurring on Staten Island, 

 eight on Long Island, seven on Martha's Vineyard, and four 

 on Block Island. Eleven of the Matawan species reappear 

 in the Atane beds of Greenland, and one additional in the 

 Patoot beds ; of these several are dominant forms of great 

 vertical or areal distribution, or both, and thus have little sig- 

 nificance ; such forms are Sequoia Rcichenbachi^ Safindus 

 Morrisoni^ Laurus -plutonia and Andromeda Parlatorii. 

 Others are more suggestive ; thus, exclusive of its occurrence 

 in the clays at Aachen, Moriconia is confined to the ancient 

 Atlantic coastal plain and Greenland, and its remains are com- 

 mon ; several species of Magnolia emphasize the similarity 

 of these floras, as does the presence of the large-leaved Aralia 

 Ravniana. This species is confined to the Atane and Mata- 

 wan floras in so far as I can judge from the published descrip- 

 tions or figures of Aralias, and its remains are unmistakably 

 characterized. Dczvalquea Grocnlandica is also confined to 

 these floras. With the Potomac flora as elaborated by Fon- 

 taine there seems to be no affinity, and the time that elapsed 

 between them must have been very long. 



Of species which occur in the Cenomanian of Europe we 

 have Geinitzia formosa^ Sequoia Reichenbachiy Cunning- 

 haviites squajnosus, Cunninghamitcs elcgans, Moriconia cyclo-
